Cardiac-1 Rapid Test

Troponin I

INTENDED USE:   The Cardiac-1 Rapid Test is intended for the in vitro diagnostic use in the qualitative  detection  of cardiac Troponin I in human serum, plasma, or whole blood samples.


Features and Advantages of Cardiac-1 Rapid Test

  • Highly sensitive chromatographic immunoassay

  • US FDA 510(K) approved test

  • Specific detection of cardiac Troponin I, the current gold standard biochemical indicator for acute myocardial infarction (AMI)

  • Rapid test format delivers results in minutes

  • Strong prognostic value in unstable angina

 Advantages of cardiac Troponin I as a cardiac Marker

  • More sensitive and specific indicator of AMI than CK-MB

  • Allows timely triage of chest pain patients into appropriate treatement and risk categories

  • Levels elevated for 5-7 days, providing a longer diagnostic window

  • Strong Prognostic value in unstable angina

Potential Utilities in the following Clinical Presentations

  • Chest pain with nondiagnostic ECG

    • elevation in Troponin I specific indicator for acute myocardial infarction (AMI)

    • negative assay results in sequential testing may allow rule-out of infarction

  • Chest pain, abnormal ECG with creatine kinase (CK) elevation following trauma or surgery

    • cardiac Troponin I helps differentiate true or false positive for myocardial cell damage

  • Persistent Chest pain prior to office/hospital presentation

    • prolonged elevation renders Troponin I sensitive indicator of AMI for up to 7 days

  • Decompensated heart failure, acute myocarditis, hypotension, syncope or prolonged

    • tachyarrhythmia

    • Troponin I assay able to detect small amounts of myocardial necrosis

Performance Characteristics

  • Cut-off positivity concentrations-1.5 ng/ml free Troponin I or 5 ng/ml ternary complex

  • Excellent correlation with commercially available ELISA assay:
